PHP Array to Object converter is a PHP class that can be used to turn any array into an object. It takes an array and assigns the variables of the class with the values of the array entries with the same name. Array entries with array values are also converted to objects recursively.

ised is a command-line tool for generating number sequences and arithmetic evaluation. Unlike big GUI-based software (such as Mathematica, Derive, Matlab, or Octave), ised is intended for use in shell scripting, together with the GNU core utilities. Its main advantage is that all functions are generalized to operate on one-dimensional arrays. It can be used for loop indexing (much like seq), line-by-line arithmetic processing of files, floating point math for shells that don't support it natively, or interactive expression evaluation (i.e. as an extended calculator).

MDArrayEngine is a JavaScript class that eases the creation and manipulation of two dimensional arrays. Although this class is not all-encompassing by any means, it should assist assist you with any JavaScript projects incorporating multi-dimensional array use.

Grid Engine (C++) is a C++ templated data structure for storing grids of information.
The grids may be connected in a D4 (Manhatten),
D8,
or hexagonal sense.
The grids may also wrap toroidally so their edges are connected.

Grid Drafter is a lightweight utility for managing two-dimensional integer grids.
It can handle either square or hexagonal grids.
Pressing keys 0-9 sets the data to be stored in a cell when you click on it.
Each number is displayed as a different color.

The List processor class lists data from arrays in HTML tables. The listing may be paginated to limit the number of array entries to display per page. The table header title and other column data formatting properties are configurable parameters. Some columns may be formatted as links or as numbers. A total value may be displayed at the bottom of a column. Control column changes can be used to generate control totals.
